Abstract

In recent years organometal halide perovskite structures have emerged as an inexpensive and revolutionary family of photoactive semiconductors in thin-film PV: arguably the biggest disruption to photovoltaics development in 60+ years since Bell Labs revolutionized silicon – Science Magazine touted it as ‘one of the top scientific breakthroughs of 2013’. Although power conversion efficiency (PCE) for high performance devices is currently recognised as 21.02% (0.1cm2) / 15.0% (1.017cm2), module efficiencies are the next logical step to be recognised (early reports indicate 6-8% PCE). Nevertheless, emerging photovoltaic (PV) technologies such as Perovskite solar cells, although showing extremely encouraging performance, present significant measurement challenges compared to more established PV technologies.In this presentation I’ll give an overview of CSIRO (The Australian, Commonwealth Industrial Research Organisation) and the Solar Energy Systems Research Group and expand on our collaborative research program into thin-film perovskite photovoltaic. I’ll describe our investigation of processes for large-area deposition and perovskite film formation toward ‘solution-less’ fabrication of glass cells and modules and our undertaking in the development and dissemination of best-practice guidelines to promote a culture of high accuracy measurement excellence in Australia.Further, I’ll present parallel studies into large-grain crystal growth via a modified interdiffusion method to improve crystallisation and film planarity and the application of a ‘metal-free’ all-carbon electrode that surpasses TCO coatings whilst retaining flexibility.
